I run a 1.66 Ghz Duo Core with 512 RAM. I had rebuilt my OS about a month ago, started it as Windows XP SP2. then I updated it to Windows XP SP3 and installed all the latest updates about 90 of them. Since then my computer is processing slow, taking more time than usual to load on boot up, slower gaming applications etc.
I've been defragmenting on weekly basis, cleaning up temporary files etc. I guess if it is because of the updates that I've installed then how does it make your computer run slow than normal?
